New principle of organization of working process of air conditioning systems at railway and sea transport
An indispensable component of ensuring safe control of railway and sea transport in conditions of hot climate is maintenance of comfortable temperature of air in control cabins and living spaces. Now the interest is restored to use the Air Refrigerating Plants (ARP) as they have a wide potential of...
